[@juliethmelado8647]

Hello sir Goodevening. I would like to asked for help how to answer this problem. An open cylinder 1.5 m in diameter and 5 m high is to be submerged in such way that the open top will be facing seawater surface (SG = 1.025). If the depth of the fluid inside the tank is 20.5 m from the seawater surface, what is the volume of the air present inside the cylinder?
